Hold 1-2 1.3 Amps main bias.
Hold 3-4 .375 Amps HOT cathode. Could be the problem, as mentioned, tie to gnd to see.
Or, the problem may be in the V10 area,

Pin 3 of V11 tests fine to GND.
Good catch on the 140v measured at the HO anode cap. It seems to have jumped back up. Suspecting an intermittent somewhere - cold joint?
Still suspicious of the Fly and will need to test for shorts between pri and sec. If not, there's got to still be an issue in the damper section.
Complete lack of boost and HV says flyback to me. Hope I'm wrong.
